Development of a portable low-frequency electronic pulse analgesia apparatus based on single-chip microprocessor / 医疗卫生装备

In this paper, a novel portable low-frequency electronic pulse analgesia apparatus is introduced, which is based on a novel single-chip microprocessor, switching power supply without transformer and OTL power output amplifier. Through this apparatus, multi-group low-frequency electronic pulses can be produced to simulate the same effects as acupuncture. This apparatus has an observably curative effect for dysmenorrhea.
